DETAILED DESCRIPTION

FIG. 1 is a block diagram of a system for evaluating quality of digital content based on user feedback obtained through a haptic interface, according to an embodiment of the invention. In particular. FIG. 1 illustrates a system 100 for evaluating digital content based on intentional user feedback obtained through user interaction with haptic feedback markers that are included in digital content, according to an embodiment of the invention. In general, the system 100 of FIG. 1 comprises a content generation system 110 which comprises an automatic composition module 120, and a content access and delivery module 130. The system 100 further comprises a computing device 140 that is configured to communicate with content generation system 110 over a computer network (e.g., wireless and/or wired LAN or WAN, global computer network (e.g., Internet), etc) to access digital content 150 that is generated and delivered by the content generation system 110. The user computing device 140 executes an application that is configured to render and present the digital content 150 that is generated and delivered by the content generation system 110, and to collect intentional user feedback through user interaction with haptic feedback markers that are included in the digital content. The system 100 further comprises a user feedback processing system 160 comprising a data analytics module 170 and an intentional user feedback evaluation engine 180, which are configured to process intentional user feedback data that is captured and collected by the computing device 140, and evaluate the quality of the digital content 150 based on the intentional user feedback and other information, as will be discussed in further detail below.

The content generation system 110 is configured to automatically generate digital content for a given type of application. In particular, the automatic composition module 120 is configured to automatically generate digital content (e.g., digital educational material) using a data store of composition rules 122, a data store of digital content components 124, a data store of haptic feedback markers 126, and a data store of profile information 128. In one embodiment of the invention, the content generation system 110 is configured to generate digital educational content, which can be accessed and utilized by group of students for a given educational subject. While embodiments of the invention can be implemented with other types of digital content, for illustrative purposes, exemplary embodiments of the invention will be discussed in the context of digital education material.

The composition rules 122 provide a set of rules for composing digital content using a set of digital content components 124 (e.g., multimedia components). In general, the composition rules 122 specify what material is to be presented and how the material is to be constructed, positioned, and otherwise presented when rendered on a computing device. For example, the composition rules 122 may specify that a given picture be displayed on a given page with a certain description, wherein the picture is displayed at a given size and the text description displayed in a given font and size, etc. Methods for automatically constructing digital content based on composition rules are well known in the art and, thus, a detailed explanation of the content generation process is not necessary for understanding embodiments of the invention.

The automatic composition module 120 applies profile information 128 to guide the composition process and generate digital content that is customized for a target individual or a target group of individuals. For example, the profile information 128 comprises individual profile information for various types of individuals and group profile information for a given target social setting (e.g., groups of students, the way the student are disposed in classes, parameters related to their social relationships, etc.). The profile information 128 is utilized in conjunction with the composition rules 122 to customize the content generation (e.g., educational content) for a given individual or a target group of individuals (e.g. schools in a given region, individual schools, classrooms, other group formation, etc.) based on the profile information associated with the given individual or target group of individuals. For example, the composition rules may specify what specific digital content components 124 should be used to generate digital content for delivery to a specific individual or group of individuals based on various factors including, but not limited to, their demographics, gender, ages, etc.

The pages of digital content 150 are generated using various content components 152 (included in the data store of content components 124) along with one or more haptic feedback markers 154 (included in the data store of haptic feedback markers 126). The haptic feedback markers 126 include various interaction components, such as like/dislike buttons, check lists, and other types of interaction elements, which implement a haptic interface that allows a user to provide feedback as to whether the user likes or dislikes a given content component within a given page of the digital content 150, which is accessed and viewed by the user. The haptic feedback markers 126 are customized for the given haptic interface and contextualized within pages of the digital content 150.

The content access and delivery module 130 is configured to enable individual users or groups of users to register with the content generation system 110, provide relevant profile information, and download digital content (either push or pull) that is automatically generated by the content generation system 110. The content access and delivery module 130 can be implemented using known front-end API techniques for accessing and interacting with web applications, for example The content access and delivery module 130 is configured to communicate with the user computing device 140 and deliver pages of digital content 150 for rendering and presentation to a user.

The user computing device 140 is may be any type of computing device, such as a desktop computer, electronic tablet, smart phone, etc. which is configured to execute an application to render and present pages of the digital content 150 and to provide a haptic interface to collect intentional user feedback resulting from user interaction with haptic feedback markers that are presented within the rendered content pages. As shown in FIG. 1, the digital content 150 comprises a rendered content pages that comprises a plurality of n content components 152 (Component 1, . . . Component n), and a plurality of m haptic feedback markers 154 (Haptic Marker 1, . . . , Haptic Marker m). It is to be understood that while FIG. 1 shows a single user computing device 140, the same digital content 150 can be downloaded to a plurality of computing devices that are used by different individuals within a given group (e.g., a plurality of students within a given classroom studying a given topic such as History). As an individual or group of individuals review and interact with pages of the digital content 150 presented on their respective computing device 140, the individual(s) can provide intentional feedback regarding their opinion on the quality of the digital content 150 (e.g., feedback regarding particular components 152) through interaction with the haptic feedback markers 154.

The user computing device 140 comprises a haptic interface which captures and stores the user interaction events with the haptic feedback markers 154 for access by the user feedback processing system 160. In general, the user feedback processing system 160 implements methods to collect, index, group, and analyze the distinct characteristics of the intentional user interaction with haptic feedback markers, and correlate such information to individual profiles of the users and social setting information (e.g. the groups of students, the way they are disposed in classes, and parameters related to their social relationships). The process generates a report of summarized group reaction towards the generated digital content in terms of organization of memory and learning, focus and attention, perception, categorization and preference, motivation and performance, learning, and others factors. The report can be utilized to evaluate the quality of the digital content 150, and thus validate the quality of the composition rules 122 being applied to generate digital content.

Overall, the system 100 of FIG. 1 implements a protocol to validate the process of automated composition of digital content by providing methods to validate the parameters being applied by the composition rules. This process leads to possible reconsideration, optimization and adjustment of parameters of the composition rules with the goal of continually improving the content generation process through subjective evaluation of composition rules by analyzing the intentional feedback input obtained through the haptic feedback markers inserted in the digital content during the composition phase.

In the user feedback processing system 160, the data analytics module 170 receives the user interaction events (e.g., interaction with the haptic interface) from the computing device 140, and stores, indexes and aggregates the interaction events in the form of intentional user feedback data that is maintained in a data store of intentional user feedback data 162. The data analytics module 170 further maintains a data store of profile information 164, which includes profile information maintained in the data store of profile information 126 utilized in the content generation system 110.

The intentional user feedback evaluation engine 180 utilizes a data store of classification rules and data 166 to process the intentional user feedback data 162 and profile data 164 provided by the data analytics module 170 and generate information that is stored and maintained in a data store of evaluation results and reports 168. The intentional user feedback evaluation engine 180 compiles distinct features of intentional user feedback obtained through haptic feedback markers 154 within pages of digital content 150 and the group behavior towards the digital content 150, which is maintained and stored in the data store of intentional user feedback data 162. The intentional user feedback evaluation engine 180 correlates this information to the profile data 164 and social setting information used by the composition rules 122 to generate reports of summarized group reaction towards the generated digital content in terms of, e.g., organization of memory and learning, focus and attention, perception, categorization and preference, motivation and performance, learning, and other factors.

As noted above, embodiments of the invention can be implemented in the context of digital educational material. For example, assume that a private school implements an educational program to deliver digital educational content to its students. In the context of the system 100 of FIG. 1, the digital educational content is generated by the content generation system 110. In this embodiment, the digital content components 124 would include various components of digital educational material related to one or more subjects. The automatic composition module 120 would compose the digital educational content using relevant composition rules 122 and profile information 128 to create customized educational material for the students based on profiles of the individual students and based on their social setting (e.g., the groups of students, the way the students are disposed in classes, and parameters related to their social relationships). Moreover, the automatic composition process would insert one or more relevant haptic feedback markers 126 within the digital educational material to provide an interface for the students to intentionally evaluate content components 124 of the digital educational content pages.

The digital educational content is delivered to computing devices that are used by the students to access and view the digital educational content. For example, the students within a given classroom could use electronic tablet computing devices or laptop computers, which would have an application for accessing and rendering the digital educational content, as well as a haptic interface for processing user feedback provided by user interaction haptic feedback markers that are displayed or otherwise rendered on pages of the digital educational content pages. For example, a student could click on a given region on a screen display of a haptic interface or upon a specific portion of displayed digital education material to open a feedback input screen where the student can make a selection. It is expected that a variation in context, such as the individual's profile and social setting, will influence how the individual interacts with the haptic feedback markers. For example, individuals of different ages and/or from diverse socio, educational, and cultural backgrounds (e.g. level of education, previous knowledge about the content, social pressures, education environment, etc.) will interact with the haptic interface distinctively, e.g., an elderly person either being more precise and soft while pushing a positive feedback button or being more “aggressive” in the same movement for negative feedback due to distress.

The haptic interface executing on the user computing device 140 registers the intentional user feedback being input as well interaction information with regard to how individual interacts with the haptic feedback markers 154. This interaction information may include, for example, a position where the user taps on a screen surface in a region of a haptic interface, the tap pressure, finger movements upon the feedback markers, and other types of interaction information that would provide a unique signature of the intentional feedback by an individual. Such information could be indicative of the individual's distress, anxiousness, satisfaction or some other feeling toward certain content, which can be used to further evaluate the individual's interaction with the digital educational material. For instance, a user can select a “like” button (haptic, feedback marker) to provide intentional feedback regarding the user's satisfaction with certain digital content. If the user taps hard on the “like” button (high pressure tap on interactive screen), this can be indicative of the user being highly satisfied with the given digital content.

These feedback events are registered and processed by the data analytics module 170 in the user feedback processing system 160. The intentional user feedback evaluation engine 180 implements statistical analysis methods to cross-relate the intentional user feedback data 162 and the profile data 164 to generate utilization reports that summarize intentional reactions from the group of students towards the digital educational content in terms of organization of memory and learning, focus and attention, perception, categorization and preference, motivation and performance, learning, and other factors. Thereafter, system administrators, educators, and/or other individuals can apply this information to manually fine-tune the parameters in the composition rules 122 that are applied to generate the digital educational content for the specific target group of students. By repeating this process, the quality of the digital educational content being provided to the students can be improved over time.

FIG. 2 is a flow diagram that illustrates a method for automatic evaluation of intentional user feedback obtained through a haptic interface, according to an embodiment of the invention. In one embodiment of the invention, FIG. 2 illustrates a process flow implemented by the intentional user feedback evaluation engine 180 of FIG. 1. Therefore, for purposes of illustration, the method of FIG. 2 will be discussed in the context of the system of FIG. 1. An initial step in the process flow includes accessing relevant intentional user feedback data obtained through interaction with haptic feedback markers (block 200). For example, as depicted in FIG. 2, the intentional user feedback evaluation engine 180 will obtain intentional user feedback data 200A from the data analytics module 170, which collects the registers of intentional user feedback information received from the computing device 140.

Next, the intentional user feedback evaluation engine 180 executes a method to evaluate each gesture on a per user basis (block 202). For this process, the intentional user feedback evaluation engine 180 uses the intentional user feedback data 200A, as well as gesture classification rules 200B, rules to classify gestures per profile 200C, and user profile data 200D. This process generates evaluation results 200E that provide an evaluation of the feedback results and gestures per user per component. This process will be further explained with reference to the data structures shown in FIGS. 3, 4, 5, 6 and 7.

FIG. 3 illustrates a data structure comprising intentional user feedback data, according to an embodiment of the invention. In particular, FIG. 3 illustrates a data structure 200A in the form of a table that includes various fields for storing intentional user feedback data. The fields include a User index (User), a Component index (Component), a Feedback index (FB#), a Gesture index (Gesture), and user feedback information (FB). The User index provides an index number for each of a plurality of users (e.g., user U1 and user U2). The Component index lists an index for a given component (e.g., Component 1). The Feedback index (FB#) provides an index for each feedback provided by a given user for a given component. For example, FIG. 3 shows that a first user U1 provided feedback for Component 1 on two separate occasions. The Gesture index provides an index that identifies the given gesture (as explained below in FIG. 4). The feedback information (FB) identifies the user's subjective feeling toward the given component. For example, a negative feedback is represented by the symbol “−” while a positive feedback is represented by the symbol “+”. Accordingly, the intentional user feedback information 200A comprises, among others, a listing of each user's input per component, along with associated gesture, which is collected and organized by the data analytics module 170.

FIG. 4 illustrates a data structure comprising gesture classification rules, according to an embodiment of the invention. In particular, FIG. 4 illustrates a data structure 200B in the form of a table that includes various fields for storing information regarding a basic classification of gestures. The fields include a Gesture index field and a Description field. The Gesture index field provides an index number for each of a plurality of different gestures that a user may make while interacting with digital content components or associated haptic feedback markers. For example, as shown in FIG. 1, a “Tap Soft” gesture is assigned an index of 1, while a “Tap Strong” gesture is assigned an index of 2. As noted above, a haptic interface may include a pressure sensor to determine an amount of pressure that is applied to the display screen when a user is selecting a given element that is displayed on the screen. The magnitude of the force that the user applies to the screen is information that can be indicative of the user's feeling in making the selection.

FIG. 5 illustrates a data structure comprising rules to classify gestures on a per profile basis, according to an embodiment of the invention. In particular, FIG. 5 illustrates a data structure 200C in the form of a table that includes various fields for storing information to cross-relate the basic classification of gestures (in Table 200B) with the “meaning” of the gestures for specific user profiles. The fields include a Profile index field, a Gesture index field, and a Meaning field. The Profile index field lists a given predefined user profile (e.g., P1, P2, etc.). The Gesture index field provides an index number for a given gesture as classified in table 200B of FIG. 4. The Meaning field specifies the meaning of the given gesture by a user having the given profile. For example, as shown in FIG. 5, for a user having a profile of P1, it is assumed that Gesture 1 (e.g., Tap Soft) would provide an indication of the user's satisfaction (like) with given content, while the Gesture 2 (e.g., Tap Strong) would provide an indication of the user's dislike of the given content.

FIG. 6 illustrates a data structure comprising user profile data, according to an embodiment of the invention. In particular, FIG. 6 illustrates a data structure 200D in the form of a table that includes various fields to store a classification of user profiles based on information such as demographics, socio-cultural background, education background, historic of manipulation of haptic interface content, and/or other information. The fields include a User index field and a Profile index field. The column of User index fields provides a listing of each of a plurality of users (e.g., U1, U2, U3, U4 . . . ). The column of Profile index fields provides a user profile (e.g., P1, P2, P3) that is assigned to each User index. For example, in table 200D, users U1 and U2 are assigned the same profile P1, while users U3 and U4 are assigned profiles P2 and P3, respectively.

Referring back to FIG. 2, the information within tables 200A, 200B, 200C, and 200D is processed by the intentional user feedback evaluation engine 180 (in block 202) to generate the evaluation results 200E shown in FIG. 7. In particular, FIG. 7 shows a table data structure 200E having various fields to store the computed feedback results and the gestures used to select the associated user feedback, grouped per user, for the interaction to each component of the digital content. The fields include the same User index field, the Component field, and feedback index field (FB#) included in the data structure 200A shown in FIG. 3, as well as Gesture Evaluation field. In FIG. 7, the Gesture Evaluation field specifies the evaluation results as +, − or 0 symbols, wherein + denotes like, — denotes dislike, and 0 denotes neutral.

Next, the intentional user feedback evaluation engine 180 executes a method to evaluate the user feedback on a per component basis (block 204). For this process, the intentional user feedback evaluation engine 180 uses the evaluation results 200E (FIG. 7) and the intentional user feedback data 200A (FIG. 3) to generate evaluation results 200F that provide a user evaluation of each component in the digital content. The process (block 204) cross-relates the evaluation results 200E with the intentional user feedback data 200A (FIG. 3) to generate the evaluation results 200F shown in FIG. 8. In particular, FIG. 8 shows a table data structure 200F having various fields to store the results of the component evaluation. The fields include the same User index field and the Component field as shown in FIG. 3, as well as Component Evaluation field. In FIG. 8, the Component Evaluation field specifies the evaluation results as ±, − or 0 symbols, wherein + denotes like, − denotes dislike, and 0 denotes neutral.

Referring back to FIG. 2, as a next step in the process, the intentional user feedback evaluation engine 180 executes a method to evaluate each component on a per group basis (block 206). For this process, the intentional user feedback evaluation engine 180 uses the evaluation results 200F (FIG. 8), the user profile data 200D (FIG. 6), as well as group profile data 200G (shown in FIG. 9), to thereby generate evaluation results 200H (FIG. 10). The process (block 206) cross-relates the evaluation results 200F with user profile data 200D (FIG. 6) and group profile data 200G (FIG. 9) to generate the evaluation results 200H (FIG. 10).

FIG. 9 illustrates a data structure comprising group profile data, according to an embodiment of the invention. In particular, FIG. 9 illustrates a data structure 200G in the form of a table that includes various fields to store a classification of group profiles, wherein the group profiles are generated by combining information of individuals in a group based on information contained in the user profile data table 200D (FIG. 6). The fields include a Group index field and a Profile index field. The column of Group index fields provides a listing of each of a plurality of groups of users (e.g., G1, G2, G3, G4 . . . ). The column of Profile index fields includes user profiles (e.g., P1, P2, P3) that are assigned to each Group index. For example, groups G1 and G2 are specified to include information regarding user profile P1, while groups G3 and G4 are specified to include information regarding user profiles P2 and P3, respectively.

FIG. 10 shows a table data structure 200H having various fields to store information related to the evaluation results for each component on a per group basis. The fields include the Group index field, the Component index field, and corresponding Component Evaluation results field. In FIG. 10, the Component Evaluation field specifies the evaluation results as +, − or 0 symbols, wherein + denotes like, − denotes dislike, and 0 denotes neutral. For example, FIG. 10 illustrates that a group of users with group profile G1 tend to like the Component 1, but tend to dislike Component 2.

Referring back to FIG. 2, as a next step in the process, the intentional user feedback evaluation engine 180 uses the evaluation results 200H to determine a quality of the composed digital content (block 208). With this process, the intentional user feedback evaluation engine 180 executes method to determine an overall rating for the composed digital content considering the evaluation results 200H to generate quality data 200I. The quality data 200I provides a rating of the quality of the composed digital content, e.g., Low, Averages, Good, etc.

The intentional user feedback evaluation engine 180 then executes a report generating process (block 210) to generate a report 200J using the quality data 200I and the evaluation results 200H. In one embodiment of the invention, the report 200J summarizes the information provided by the quality data 200I and the determined group evaluations per component as set forth in the evaluation results 200H. Thereafter, the report 200J can be utilized by system administrators, educators, and other parties to evaluate the quality of the digital content, thus validating the quality of the composition rules 122 that are used to generate the digital content. If desired, the system administrator, etc., can manually modify the composition rules 122 with the goal of improving the quality of the digital content being generated by the automated content generation process to specific individuals or specific groups of individuals, etc.

FIG. 11 is a block diagram of a system for evaluating quality of digital content based on user feedback obtained through a haptic interface, according to another embodiment of the invention. In particular, FIG. 11 illustrates a system 300 for evaluating digital content based on non-intentional user feedback obtained through user interaction with digital content, according to an embodiment of the invention. In general, the system 300 of FIG. 11 comprises a content generation system 310 which is similar to the content generation system 110 discussed above with reference to FIG. 1. However, the content generation system 310 in FIG. 11 does not include a data store of haptic feedback markers 126 (as shown in FIG. 1). Instead, in the embodiment of FIG. 11, the content generation system 310 generates digital content 350 which comprises a plurality of components (e.g., Component 1, . . . Component n) using methods as discussed above, but without specific haptic feedback markers as included in the digital content 150 shown in FIG. 1.

The system 300 of FIG. 11 provides for non-subjective evaluation of automatically generated digital content (e.g., education material) based on non-intentional signals obtained through a haptic interface implemented by the user computing device 140. The user computing device 140 in this embodiment comprises a haptic interface that is configured to capture and collect non-intentional signals generated by user manipulation of the digital content 350. The non-intentional signals include, for example, finger interaction with components of the digital content 350 such as gestures, tactile manipulation, contact, zooming actions, tapping, and others interactions. The user computing device 140 outputs this information as utilization events to a user feedback processing system 360.

In the exemplary embodiment of FIG. 11, the user feedback processing system 360 implements methods to collect, index, group, and analyze the distinct characteristics of the non-intentional user interaction with components of the digital content 350, and then correlate this information to individual user profiles and social setting information (e.g. the groups of students, the way they are disposed in classes, and parameters related to their social relationships). Similar to the system 100 of FIG. 1, the process of FIG. 11 generates a report of summarized group reaction towards the generated digital content in terms of organization of memory and learning, focus and attention, perception, categorization and preference, motivation and performance, learning, and others factors. In particular, the system 300 of FIG. 11 implements a protocol to validate the process of automated composition of digital content by providing methods to validate the parameters being applied by the composition rules based on non-intentional user feedback. This process leads to possible reconsideration, optimization and adjustment of parameters of the composition rules with the goal of continually improving the content generation process through non-subjective evaluation of composition rules through analyzing the non-intentional feedback input obtained through user interaction with components of the digital content via the haptic interface.

More specifically, in the user feedback processing system 360, a data analytics module 370 receives the user utilization events from the computing device 140, and stores, indexes and aggregates the utilization events in the form of non-intentional user feedback data that is maintained in a data store of non-intentional user feedback data 362. The data analytics module 370 further maintains a data store of profile information 364, which comprises information that is maintained in the data store of profile information 126 utilized in the content generation system 310.

A non-intentional user feedback evaluation engine 380 utilizes a data store of classification rules and data 366 to process the non-intentional user feedback data 362 and profile data 364 provided by the data analytics module 370 and generate information that is stored and maintained in a data store of evaluation results and reports 368. The non-intentional user feedback evaluation engine 380 compiles distinct features of non-intentional user feedback obtained through user interaction and manipulation of components of the digital content via the haptic interface, and group behavior towards the digital content 350. The non-intentional user feedback evaluation engine 380 correlates this information to the profile data 364 and social setting information used by the composition rules 122 to generate reports of summarized group reaction towards the generated digital content in terms of, e.g., organization of memory and learning, focus and attention, perception, categorization and preference, motivation and performance, learning, and other factors.

As noted above, embodiments of the invention can be implemented in the context of digital educational material. An illustrative scenario for processing non-intentional user feedback signals is similar to that discussed above with regard to a private school that implements an educational program to deliver digital educational content to its students. In this example, the educational digital content is delivered to students who interact and manipulate the digital content while viewing the content on a laptop computer or electronic tablet, for example. A haptic interface executing on the computing device 140 of each student registers non-intentional signals generated by the manipulation of the digital educational material, such as tactile manipulation, gesture, the way students tap upon specific components, the components that students zoom in on, and give more attention to, time to change pages, clicks on hyperlinks for alternative content, and others types of interaction. In this scenario, it is expected that variation of context, such as end-users' profile and social setting, will influence on how the end-user interacts with the digital educational material. For example, a student in distress and/or with previous knowledge of the content being presented, will tend to turn the pages faster and avoid zooming in on specific parts. Whereas, students with interest and no previous knowledge of the content will interact with more elements, stay longer in specific pages, and so on.

These non-intentional user feedback events are acquired and registered by the data analytics module 370 as non-intentional user feedback data 362. The non-intentional user feedback evaluation engine 380 implements methods to cross-relate the non-intentional user feedback data 362 derived from (i) the student's non-intentional signals acquired through the manipulation of the digital educational material via the haptic interface, and Digital Content Material through the Haptic Interface, and (2) the profile data of the students. The non-intentional user feedback evaluation engine 380 generates utilization reports that summarize non-intentional signals from groups of student towards the generated digital educational material in terms of organization of memory and learning, focus and attention, perception, categorization and preference, motivation and performance, learning, and others. Thereafter, system administrators, educators, and other parties can apply this information to fine-tune the parameters in the composition rules 122 being applied to generate the digital educational material for the specific group of students. This process will continuously improve the quality of educational digital content being provided to the students over time.

FIG. 12 is a flow diagram that illustrates a method for automatic evaluation of non-intentional user feedback obtained through a haptic interface, according to an embodiment of the invention. In one embodiment of the invention, FIG. 12 illustrates a process flow implemented by the non-intentional user feedback evaluation engine 380 of FIG. 11. Therefore, for purposes of illustration, the method of FIG. 12 will be discussed in the context of the system 300 of FIG. 11. An initial step in the process flow includes accessing relevant non-intentional user feedback data obtained through interaction with a haptic interface (block 301). For example, as depicted in FIG. 11, the non-intentional user feedback evaluation engine 380 will obtain non-intentional user feedback data 300A from the data analytics module 370, which collects the registers of non-intentional user feedback information received from the computing device 140.

Next, the non-intentional user feedback evaluation engine 380 executes a method to evaluate each gesture on a per user basis (block 302). For this process, the non-intentional user feedback evaluation engine 380 uses the non-intentional user feedback data 300A, as well as gesture classification rules 300B, rules to classify gestures per profile 300C, and user profile data 300D. This process generates evaluation results 300E which provides an evaluation of the feedback results and gestures per user per component. This process will be further explained with reference to the data structures shown in FIG. 13, for example.

FIG. 13 illustrates a data structure comprising non-intentional user feedback data, according to an embodiment of the invention. In particular, FIG. 13 illustrates a data structure 300A in the form of a table that includes various fields for storing non-intentional user feedback data. The fields include a User index (User), a Component index (Component), and a Gesture index (Gesture). The User index provides an index number for each of a plurality of users user U1 and user U2). The Component index lists an index for a given component (e.g., Component 1). The Gesture index provides an index that identifies the given gesture (non-intentional user feedback signal). Accordingly, the non-intentional user feedback information 300A comprises, among others, a listing of non-intentional feedback signals per user per component, which is collected and organized by the data analytics module 370. Moreover, example embodiments of the gesture classification rules 300B, rules to classify gestures per profile 300C, and user profile data 300D are similar to the data structures 200B, 200C and 200D shown in FIGS. 4, 5, and 6 and, therefore, a detailed discussion need not be repeated.

Referring back to FIG. 12, the information within tables 300A, 300B, 300C, and 300D is processed by the non-intentional user feedback evaluation engine 380 (in block 302) to generate the evaluation results 300E shown in FIG. 14. In particular, FIG. 14 shows a table data structure 300E having various fields to provide information regarding the evaluation results for the non-intentional gestures per user per component. The fields include the User index field, the Component field, and a Gesture Evaluation field. In FIG. 14, the Gesture Evaluation field specifies the evaluation results as +, − or 0 symbols, wherein + denotes like, − denotes dislike, and 0 denotes neutral.

Referring back to FIG. 2, as a next step in the process, the non-intentional user feedback evaluation engine 380 executes a method to evaluate each component on a per group basis (block 304). For this process, the non-intentional user feedback evaluation engine 380 uses the evaluation results 300E (FIG. 14), the non-intentional user feedback data 300A (FIG. 13), as well as user profile data 300D and group profile data 300G, to thereby generate evaluation results 300H. The process (block 304) cross-relates the non-intentional user feedback data 300A (FIG. 13) with the group profile data 300G (e.g., FIG. 9) to generate the evaluation results 300H. In one embodiment of the invention, the evaluation results 300H are similar in content and structure to the evaluation results 200H shown in FIG. 10 and, therefore, a detailed discussion need not be repeated.

Next, the non-intentional user feedback evaluation engine 380 uses the evaluation results 300H to determine a quality of the composed digital content (block 306). With this process, the non-intentional user feedback evaluation engine 380 executes method to determine an overall rating for the composed digital content considering the evaluation results 300H to generate quality data 300I. The quality data 300I provides a rating of the quality of the composed digital content. e.g., Low, Averages, Good, etc.

The non-intentional user feedback evaluation engine 380 then executes a report generating process (block 308) to generate a report 300J using the quality data 300I and the evaluation results 300H. In one embodiment of the invention, the report 300J summarizes the information provided by the quality data 300I and the determined group evaluations per component as set forth in the evaluation results 300H. Thereafter, the report 300J can be utilized by system administrators, educators, and other parties to evaluate the quality of the digital content, thus validating the quality of the composition rules 122 that are used to generate the digital content. If desired, the system administrators, etc., can manually modify the composition rules 122 with the goal of improving the quality of digital content material being generated by the automated content generation process.

FIG. 15 is a block diagram of a system for evaluating the quality of digital content based on user feedback obtained through a haptic interface, according to yet another embodiment of the invention. In particular, FIG. 15 illustrates a system 400 for evaluating digital content based on a combination of intentional user feedback and non-intentional user feedback obtained through user interaction with digital content, according to an embodiment of the invention. The system 400 of FIG. 15 comprises a content generation system 110 which is similar to the content generation system 110 discussed above with reference to FIG. 1. The content generation system 110 in FIG. 15 includes a data store of haptic feedback markers 126 to generate digital content 150 having a plurality of components 152 and augmented with one or more haptic feedback markers 154 for implementing a haptic interface to collect intentional user feedback data based on user interaction with the haptic feedback markers 154, as discussed above with regard to FIGS. 1 and 2, for example.

The system 400 of FIG. 15 comprises a user feedback processing system 460 that is configured to process intentional user feedback data and non-intentional user feedback data, using techniques such as discussed above with reference to FIGS. 2 and 12, for example. More specifically, as shown in FIG. 15, the user feedback processing system 460 comprises a data analytics module 470, an intentional user feedback evaluation engine 480, a non-intentional user feedback evaluation engine 482, and an engine for automatic adjustment of composition rules 490. Similar to the embodiments of the systems 100 and 300 discussed with reference to FIGS. 1 and 11, for example, the data analytics module 470 receives the user interaction events from the computing device 140, and stores, indexes and aggregates the interaction events in the form of intentional user feedback data (obtained through user interaction with haptic feedback markers 154) which is maintained in a data store of intentional user feedback data 462A, as well as non-intentional user feedback data (obtained through user interaction with content components) which is maintained in a data storage of non-intentional user feedback data 462B. The data analytics module 470 further maintains a data store of profile information 464 (comprising user and group profile data).

For example, in the context of the above illustrative scenario where students interact with the digital educational content, a haptic interface of the computing device 140 captures intentional user feedback through the haptic feedback markers 154 and registers non-intentional user feedback signals generated by the manipulation of the digital educational material. Such non-intentional user feedback signals can be signals generated as a result of tactile manipulation, gesture, based on the manner in which students tap up specific displayed elements, the elements that students zoom in on and give more attention to, the time spent on certain content pages, clicks on hyperlinks for accessing alternative content, and others types of interactions of non-intentional user feedback indicative of an individual's reaction (interest or lack of interest, neutrality, etc.) towards digital content rendered by the computing device.

Again, as noted above, it is expected that the variation of context, such as an individual's profile and social setting, will influence on how the individual interacts with the digital educational content or other content. For example, an individual in distress and/or with previous knowledge of content being presented will tend to turn the pages faster and avoid zooming in on specific elements. Whereas, in individual with interest and no previous knowledge of the content will interact with more elements, stay longer on specific content pages, and so on. As a further example, individuals of different ages and from diverse socio, education, and cultural backgrounds (e.g. influenced by level of education, previous knowledge about the content, social pressures, education environment, etc.) will interact with the haptic interface (touch screen surface) distinctively—for example, an elderly person either being more precise and soft while pushing a positive feedback button or being more “aggressive” in the same movement expressing negative feedback due to distress.

The intentional user feedback evaluation engine 480 utilizes information within a data store of classification rules and data 466 to process the intentional user feedback data 462A and profile data 464 provided by the data analytics module 470 using methods discussed above with reference to FIG. 2, for example, to generate information that is stored and maintained in a data store of evaluation results and reports 468. In particular, as noted above, the intentional user feedback evaluation engine 480 generates reports of summarized group reaction towards the generated digital content based on the intentional user input data captured through haptic feedback markers and the group behavior towards the digital content.

The non-intentional user feedback evaluation engine 482 utilizes information within the data store of classification rules and data 466 to process the non-intentional user feedback data 462B and profile data 464 provided by the data analytics module 470 using methods discussed above with reference to FIG. 12, for example, to generate information that is stored and maintained in a data store of evaluation results and reports 468. In particular, as noted above, the non-intentional user feedback evaluation engine 482 generates reports of summarized group reaction towards the generated digital content based on non-intentional user feedback signals generated by the manipulation of the digital content through a haptic interface of a computing device.

The engine for automatic adjustment of composition rules 490 is configured to utilize information contained within evaluation reports generated by the intentional and non-intentional user feedback evaluation engines 480 and 482 to automatically adjust the composition rules 122 that are used to generate the digital content. In particular, as explained in further detail below, the engine for automatic adjustment of composition rules 490 implements methods to process and analyze the summary reports (e.g., reports 200J and 300J, FIGS. 2 and 12) showing group reaction towards the generated digital content based on (i) the intentional user feedback data obtained through the haptic feedback markers 154 (e.g. buttons, check lists, and other interaction elements in haptic interfaces) and (ii) the non-intentional user feedback data (e.g. gestures, tactile manipulation, contact, zooming actions, tapping, and others).

The engine 490 is configured to analyze and cross-relate the summary report information with parameters used by the composition rules 122 and the components 152 of the generated digital Content 150. The engine 490 utilizes statistical analysis techniques to evaluate distinct characteristics of the interactions in the summary report information output from the evaluation engines 480 and 482, classifies their meaning, and infers the users' perception of the quality of the digital content in terms of organization of memory and learning, focus and attention, perception, categorization and preference, motivation and performance, learning, and others. The engine 490 applies advanced algorithms for optimization and machine learning to adjust the parameters utilized by the composition rules 122 with the goal of improving the quality of material being generated by this process. In this regard, the user feedback processing system 460 is configured to dynamically adjust and optimize the automated content composition process implemented by the content generation system 110 through the automatic optimization and adjustment of parameters of the composition rules 122.

FIG. 16 is a flow diagram that illustrates a method for automatic adjustment of content composition rules based on evaluation of intentional user feedback and non-intentional user feedback obtained through a haptic interface, according to an embodiment of the invention. In one embodiment of the invention, FIG. 16 illustrates a process flow implemented by the engine for automatic adjustment of composition rules 490 (FIG. 15). Therefore, for purposes of illustration, the method of FIG. 16 will be discussed in the context of the system of FIG. 15. An initial step in the process flow includes collecting and processing evaluation results generated for the intentional and non-intentional user feedback to determine an overall rating evaluation per each group of users per each component (block 500).

For example, in the system 400 depicted in FIG. 15, the engine for automatic adjustment of composition rules 490 will access the intentional and non-intentional user feedback data 462A and 462B, and collect information from the reports of summarized group reaction for haptic feedback markers and non-intentional gestures generated by the user feedback evaluation engines 480 and 482. This information comprises, for example, a table of evaluation results per component per group of users (e.g., information in data structure 200H, FIG. 9) and a table of evaluation results of non-intentional signals per component per group of users. The computation in block 500 yields a table of overall rating evaluation per group per component.

Next, the engine for automatic adjustment of composition rules 490 will determine an evaluation rating for each composition rule (block 502). This process cross-relates information from the table of overall rating evaluation per group per component (as determined in block 500) with a table of composition rules per component 400A (as shown in FIG. 17) and generates a table of component evaluation per composition rule 400B (as shown in FIG. 18). In particular, FIG. 17 shows a data structure 400A in the form of a table which includes various fields to store composition rules that are applied to generate each component of the digital content being analyzed. The fields include a Rule field that lists composition rule index (or Rule#), and a Component field that list an index of the associated component that was generated using the given composition rule. For example, FIG. 17 indicates that rule R1 was used to compose Component 1, and that rule R2 was used to compose Components 2 and 3, for example.

Moreover, FIG. 18 shows a data structure 400B in the form of a table which includes various fields to store an overall evaluation of each component per a composition rule applied to that component. This data structure 400B indicates, for example, that the application of composition rule R1 to compose Component 1 is favorable (i.e., + evaluation indicator), whereas the application of composition rule R2 to compose Components 1 and 2 is unfavorable.

Referring back to FIG. 16, the process (in block 502) generates an evaluation rating per composition rule, in particular, an overall evaluation rating per composition rule. For each composition rule whose evaluation rating is not negative (negative determination in block 504), e.g., the evaluation rating is positive, no adjustment is made to that composition rule (block 506). On the other hand, for each composition rule with a negative evaluation (affirmative decision in bock 504), a process is executed to determine an adjustment to that composition rule (block 508). In this process, the engine for self-adjustment of composition rules 490 will process the data structure 400B identify composition rules with negative evaluations.

In one embodiment of the invention, the process (in block 508) to determine an adjustment to a composition rule is implemented using a method which calculates an adjustment to be applied for a selected composition rule as a variation of a weight value associated with the composition rule applied to compose specific components for a target group profile. The process generates an estimate in an amount in which the given weight value is reduced taking into consideration the negative feedback that results based on the use of the given composition rule applied to compose the digital content.

The engine for automatic adjustment of composition rules 490 will use the adjustment value for a given composition rule to modify a table of composition rules 400C, as shown in FIG. 19. In particular, FIG. 19 illustrates a data structure 400C in the form of a table of composition rules comprising fields to store information regarding a list of composition rules, classified by weight, to be applied to generate specific components of digital content provided to a given group of users with certain group profiles. In particular, as shown in FIG. 19, the composition rules table 400C comprises a Rule index field, a Component index field, a Group Profile field and a Weight value field. The Weight value field specifies a weight value to be used in selecting a given composition rule to apply to compose a given component of content for a given group profile.

In the system 400 of FIG. 15, by automatically adjusting a parameter (e.g., weight value) utilized by the composition rules 122, the process implemented by the automatic composition module 120 will utilize dynamically updated composition to improve the quality of the digital content that is delivered to a target group of users. Over time, an iterative update and adjustment of the composition rules will serve to continuously improve the quality of digital content being delivered to various groups of users.
